Another Floating Blocks Optical Illusion


Our favourite professor has done it again! Akiyoshi has created showcased illusory pattern titled “Chidori” (which is some kind of a bird if I understood it correctly), which gives an impression that the inner block is moving in upper-diagonal direction. To amplify the effect, simply scroll the page up and down slightly. After a while, you’ll see the inner block floating on top of its background. If you’re lucky, you’ll experience the 3D stereoscopic effect without having to go cross-eyed or wearing those clumsy 3D glasses!

      One thing more, try not to move your eye ball and the object well definitely not waving also.

    Actualy, while Chidori IS the name for a type of bird, and a girls name (in japan) its actual meaning is ‘thousand birds chirping’.

    If you look at the picture, you can see how the squares vaugely look like very stylised birds- the little circles as eyes, the wobbly front corner beak-like, and the other side corners the wings.

    Try to get your eyes out of focus, it works better.

    Doesn’t work for me.

    Weird and wiggly, but neither moving/flowing, nor floating.

  • I see some illusions, but not the way it’s described. I can’t see “the inner block moving in upper-diagonal direction”.

  • suor de sapo

    I see it moving from lower-left to upper-right.

      wait… Now I see the “background” moving in the opposite direction :-)
